Line Differential Protection and Control RED615 IEC
Compact and versatile solution for utility and industrial power distribution systems. RED615 is a phase-segregated, two-end line differential protection and control relay for overhead line and cable feeders, including radial, looped, and meshed networks, with or without distributed generation. It also supports in-zone transformer applications. Communication between substations is via fiber-optic or galvanic pilot wire link
